Last time I looked, >messages tended to have only *ONE* From: address.. RFC822 is quite clear on this. Take the example on pages 7 and 8: So, for example, the folded body of an address field ":sysmail"@ Some-Group. Some-Org, Muhammed.(I am the greatest) Ali @(the)Vegas.WBA is analyzed into the following lexical symbols and types: :sysmail quoted string @ special Some-Group atom . special Some-Org atom , special Muhammed atom . special (I am the greatest) comment Ali atom @ atom (the) comment Vegas atom . special WBA atom The canonical representations for the data in these addresses are the following strings: ":sysmail"@Some-Group.Some-Org and Muhammed.Ali@Vegas.WBA Note: For purposes of display, and when passing such struc- tured information to other systems, such as mail proto- col services, there must be NO linear-white-space between s that are separated by period (".") or at-sign ("@") and exactly one SPACE between all other s. Also, headers should be in a folded form. This indicates that the cited address "George Bush bush@tree" is valid. The interpretation according to RFC822 might not be the intended one, but that's a different topic. The mailer creating these addresses should be checked and corrected. It is most likely something like Dq$?x$x $.$g instead of Dq$?x$x $.<$g> in its sendmail.cf (incorrect definition of total addresses). -- Juergen Wagner gandalf@csli.stanford.edu wagner@arisia.xerox.com
